IMPROVEMENT INICCDKE-OVENS.

Specification forming part of Letters Patent No. 180,010, dated July 18,1876 application filed June 12, 1876.

To all whom it may concern Be it known that I, SAMUEL DIESGHER, ofPittsburg, in the county of Allegheny and State of Pennsylvania, haveinvented certa n new and useful Improvements in Ooke- Ovens; and I dohereby declare the following to be a I full, clear,.and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it,

reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in coke-ovens; and it consists inthe construction and arrangement of gas and air lines for the purpose ofcooling by the latter the foundation and lower portions of thebrick-work of the ovens, and also for using the air, after becomingheated and intermixed with the gas escaping from the coal during theprocess of coking, to obtain an intense heat by a thorough combustion ofthe gas, as will be more fully described hereinafter.

v The accompanying drawings represent my invention.

Figure l is a side elevation, partly in section. Figs. 2 and 3 are endviews, and Figs.

4 and 5 are horizontal sections, of my invention.

A represents the combustionchamber of the oven, in which the process ofcoking coal is carried on. B are separation or partition walls betweenthe ovens. O are the arches and D the bottoms of the ovens. E representsopenings left below the skew-backs of the arches in the partition-wallsfor the escape of smoke and gas. F are flues in the partition-walls,into which the openings E der the foundation of the ovens, both in frontand rear, extending under the whole series of ovens, which fines haveopenings a for each one of the ovens under their separation-walls. Theopenings a lead to the tines I), through which the air enters thechamberc, and continues by the horizontal flue (1 into the verticalflues e, and passes through the fiuesf into the general gas-flue F,intermixing thoroughly with the gas therein, the air having during itspassage through the various flues become intensely heated.

Q and R represent the doors in front of the combustion-chamber, the oneabove the other, working independently on hinges. O are openings in thearch of each oven, for the introduction of coal; and g g g, holes ineach end of the partition-walls to permit the cleaning of the tines F.The holes P under the bottom of the ovens are for cleaning the flues Hand H. These holes 9 andP are kept closed by loose brick during theprocess of coking, and only opened when cleaning the fines is re quired.

The operation is as follows: A wood-fire is lighted incombustion-chamber, and kept up until its walls and bottom aresufficiently" heated to ignite the coal when thrown in through theopening 0, which opening, when the oven is charged, is immediatelyclosed. The upper doorR is now opened and the coal properly leveled,after whichit also is closed, when theprocess of coking begins. The gasdeveloped from the charge enters the holes E below the skew-backs of thearch, whence it passes downward into the general gas-flue F,

and thence into the fluesF, at which point it is mixed with -the heatedair issuing from the smaller fines f. The heated air thus mixed with thegas causes a thorough combustion of the latter, creating an intenseheat, which penetrates the brick walls, and contributes contity of goodcoke, and a better quality, espebitumen, the want of which makis italmost useless for the production of coke by other means.

Having thus described my invention, I claim-- 1. In a coke-oven, thecombination of the chamber A, gas-passages E, leading from its top,downwardly-descending combustion-fines F F, and air-passages 01,substantially as set forth.

i l cially when the coal used possesses but little 2. In a coke-oven,the air-fines a t, chamber a, air-passages d ef, and combustion-fines F,substantially as shown. L

In testimony that I claim the foregoing I have hereunto set my hand this31st day of May, 1876.

SAMUEL DIESOHER.
